testing

I’m trying to test by react-native testing library but I got this error

    Jest encountered an unexpected token

    This usually means that you are trying to import a file which Jest cannot parse, e.g. it's not plain JavaScript.

    By default, if Jest sees a Babel config, it will use that to transform your files, ignoring "node_modules".

    Here's what you can do:
     • If you are trying to use ECMAScript Modules, see https://jestjs.io/docs/en/ecmascript-modules for how to enable it.
     • To have some of your "node_modules" files transformed, you can specify a custom "transformIgnorePatterns" in your config.
     • If you need a custom transformation specify a "transform" option in your config.
     • If you simply want to mock your non-JS modules (e.g. binary assets) you can stub them out with the "moduleNameMapper" config option.

    You'll find more details and examples of these config options in the docs:
    https://jestjs.io/docs/en/configuration.html

    Details:

   /node_modules/react-native-flash-message/src/index.js:2
    import FlashMessageWrapper, { getFlashMessageStatusBarHeight, styleWithInset } from "./FlashMessageWrapper";
    ^^^^^^

@mustafakameldev I spent some time on it and finally, adding this to the Jest configuration helped me:

"transformIgnorePatterns": [
      "node_modules/(?!(jest-)?@react-native|react-native|react-native-flash-message/*)"
    ],
